Moss, Le Roy, Ill. i Application October 16, 1953, Serial No. 386,518 4 Claims. (Cl. 4-67) This invention relates to improved flushing mechanisms for toilet tanks and the like, and the primary object of the invention is to provide ecient and reliable mechanisms of this kind which are operable to shut olf the flow of water from flush tanks into toilet bowls or the like before the tanks are empty, and before conventional mechanisms of this kind would produce shutting off of such flow, so as to provide for the convenience and economy of using only a fraction of the water present in the tanks when desired.
Another important object of the invention is to provide improved mechanisms of the character indicated above which are relatively simple in construction, which operate easily and reliably, and which utilize standard parts of conventional flush valve mechanisms.
Other important objects and advantageous features of the invention will be apparent from the following description and the accompanying drawings wherein, for pur poses of illustration rather than limitation, specific embodiments of the invention are set forth in detail.
In the drawings:
Figure 1 is a front elevation, partly broken away, showing one embodiment with the valve mechanism in closed position;
Figure 2 is a fragmentary transverse vertical section taken on the line 2-2 of Figure l, andomitting the float;
Figure 3 is an enlarged fragmentary transverse vertical section taken on the line 3-3 of Figure l;
Figures 4, 5, and 6 are enlarged horizontal sections taken on the lines 4-4, 5-5, and 6 6 of Figure l;
Figure 7 is a view like Figure l of another embodiment of the invention; and
Figure S is a fragmentary transverse vertical section taken on the line 3 8 of Figure 7 and omitting the float. v
Referring in detail to the drawings, wherein like numerals designate like parts throughout the several views, and first to Figures l through 6, the numeral 9 generally designates a conventional form of toilet ush tank having a lid or cover 19, a front wall 12, and a bottom wall 13. The bottom wall 13 is provided with a ball valve seat 14 communicating with a pipe 15 leading to a toilet Xture (not shown).
The valve seat 14 has a lateral arm 16 from which rises an overflow pipe 17. A rubber ball valve 18, seated in the seat 14 in the closed condition of the llush mechanism, has rising axially therefrom a relatively short rod 19 terminating at its upper end in an eye 20.
A guide arm 21 has a ring 22 on one end which is circumposed on an intermediate part of the overflow pipe 17 and locked in vertically adjusted position by a set screw 23. On the other end of the guide arm 21 is a vertical sleeve 24 in which the part of the valve rod 19 below the eye 26 is slidably guide.
A U-shaped lower clamp block 25 involves spaced parallel arms 26, 26 joined at one end by a bight portion 27 provided with a vertical hole 28, and a set screw 29 entering the hole 2S. The valve rod 19 is loosely confined between the legs 26, 26 by a pin 30 passing through ICC the free ends of the legs 26, 26, as shown in Figure 6. In the closed condition of the tlush mechanism the lower block 25 rests upon the upper end of the ball valve 18, as shown in Figures 1 and 2.
A vertical operating rod 31 rises from the lower block 25 and has its lower end engaged in the hole 28 and locked in adjusted position therein by the set screw 29. The operating rod 31 has an upper end 32 which is at an elevation above the control lever 33. The control lever 33 is of conventional form, having a free end portion 34 provided with a row of holes 35 and being secured at its other end, in a well known manner, to the shank or" a conventional handle 36 located in front of the tank front wall12.
l n the arrangement shown in the drawings, the operating rod 31 is positioned at the rear of and close to the control lever 33, and an upper clamp block 37 is secured to the upper end portion of the operating rod 31 at a point above the control lever 33.
T he upper block 37 comprises a rear plate 38 provided with half round recesses 39 and 39', a front plate 40 superimposed on the rear plate 38 and provided with half round recesses 41 and 41 registered with the recesses 39 and 39', and screws 42 and 43 threaded through the front plate 40 into the rear plate 38. The upper part of the operating rod 31 is clamped between the plates 38 and 4l) in the recesses 39 and 41 and a vertical trip rod 44 has its lower part clamped between the plates 38 and 40 in the recesses 39' and 41.
A forwardly projecting hook 45 which is engaged through a selected one of the holes 35 of the control lever 33 is fixed to the rod 31 by a block 45.
As shown in Figure 3, the trip rod 44 passes upwardly through the tank cover 1t) through the smooth bore 48 of a threaded bushing 49' having a flanged head 50 engaging the top of the tank cover 10. A washer 51 is circumposed on the bushing 49 and engages the underside of the cover 10, and a nut 52 is threaded on the bushing 49 against the washer 51. The upper end of the trip rod 44 is threaded, as indicated at 53, into a trip rod knob 54.
Operatvely connecting the operating rod 31 with the ball valve rod eye 2i) is a hook 55 engaged through the eye 20 and adjustably secured to the operating rod 31 by an intermediate clamp block 56. The block 56 has a hole 57 through which the operating rod 31 is passed and a set screw 58 locks the block 56 in place on the operating rod 31. "i
With the foregoing arrangement, and the Hush tank 9 full of water,"downward swinging of the control handle 36 will swing the control lever 33 upwardly and thereby elevate the upper block 37, the operating rod 31, and raise the ball valve 18 out of its seat 14 and permit the water in the tank 9 to pass through the pipe 15 to the toilet xture. As this takes place, the oat 60, which can be conventional and -is connected by an arm 61 to a conventional water inlet valve (not shown), will subside as the water level falls until the float 63 reaches a depressed position in which the water inlet valve (not shown) will be opened to replenish the water in the tank 9, and the ball valve 18 will drop into the seat 14 and cut olf flow of water from the tank 9 to the toilet fixture, only when the tank 9 is substantially empty of water.
However, the foregoing cycle of operation, which is conventional, can be changed or omitted by manipulating the trip rod knob 54. If, for example, after initiating the above described cycle, it is desired to discharge less than the usual amount of water from the tank 9, the knob 54, which is then in an elevated position, can be pushed down, so that the lower block 25 engages and depresses the ball valve 18 into its seat 14 and closes off discharge of water from the tank at any desired point in the cycle prior to that at which the ball valve 1S would otherwise become seated.
Referring now to Figures' 7 and 8 of the drawings, there is therein shown another embodiment of the invention wherein the same effect of advanced cut-off of discharge of water from a flush tank is obtained without the use of an external trip rod knob. The structure of this embodiment includes the same parts, given the same designating numerals supplemented with the letter a, as compose the rst described embodiment of Figures l through 6, but the upper block 37, the trip rod 44, and the trip rod knob 54 are omitted.
The ball valve 18a can, in this instance, be seated in the seat 14a in advance of the usual point in the cycle of operation of the mechanism, by pulling upwardly' on the handle 36a. This will push the operating rod 31a downwardly and press the lower block a upon the ball valve 18a and depress the ball valve 18a into the seat 14n so as to retain the desired amount of water in the tank 9a.
